Chemistry Knowledge Quiz

Chemistry: The Central Science

• Chemistry is the central science that provides a foundation for understanding basic and applied scientific disciplines.

Chemistry in the Natural Sciences

• Chemistry studies the building blocks of matter, including atoms, molecules, and ions, within the natural sciences.

Interdisciplinary Connections

• Chemistry explains aspects of other scientific disciplines, such as:
  • Biology: the structure and function of biomolecules, like proteins and DNA
  • Physics: the properties and behavior of matter at the atomic and molecular level
  • Earth Science: the composition of the Earth's crust, atmosphere, and hydrosphere
  • Environmental Science: the impact of human activities on the environment

Position of Chemistry

• Chemistry is situated between physics and biology, as it:
  • Draws on the laws of physics to understand the behavior of atoms and molecules
  • Provides a framework for understanding the structure and function of biomolecules in biology

Chemical Compounds

• Compounds studied in chemistry are made up of:
  • Atoms, which are the smallest units of matter
  • Molecules, which are groups of atoms bonded together
  • Ions, which are atoms or groups of atoms with an electric charge
